On the News @ Le Matin Title:  Découverte de Nouvelles Traces de Dinosaure Excerpt: “L’environnement du Jura au Jurassique supérieur, il y a environ 152 millions d’années, se compare à celui des Bahamas d’aujourd’hui. Les variations du niveau marin y ont permis l’émersion des terres, et donc l’installation prolongée de populations de dinosaures ainsi que la préservation de leurs empreintes. Le nouveau type de traces, baptisé Jurabrontes curtedulensis, est validé

The Araraquara County (São Paulo State, Brazil) contains some of the

Just out @ Historical Biology Enigmatic didactyl tracks from the Jurassic of Iran Author(s) Lida Xing, Nasrollah Abbassi & Martin G. Lockley Abstract: Didactyl tracks of theropod affinity are reported in this study based on a small sample of footprints in sandstones within the Middle Jurassic (Aalenian-Bajocian) Dansirit Formation in the Baladeh area, Alborz Mountains, Iran. These tracks superficially resemble footprints attributed to small deinonychosaurian dinosaurs known mainly from the Cretaceous of Asia. The

Razzolini, Martin G. Lockley, Géraldine Paratte, Marielle Cattin, Christel Lovis & Christian A. Meyer Abstract: Jurabrontes curtedulensis, a new ichnogenus and species of Late Jurassic giant theropod dinosaur track is described based on very well-preserved and morphologically-distinct tracks, all carefully excavated along federal highway A16 (Canton

Just out @ Cretaceous Research A new mammal track from the Laramie Formation (Maastrichtian) at the Fossil Trace locality, Golden, Colorado Author(s) Martin G. Lockley, Neffra A. Mathews, Brent Breithaupt Abstract: A previously unknown and morphologically distinct pentadactyl mammal track was recovered from the Upper Cretaceous (Maastrichtian) Laramie Formation at the Fossil Trace site, a National Natural Landmark which it’s the type locality for Schadipes crypticus, the only named mammal track known from North

Just out @ PalZ Palaxius salataensis Brönnimann, Cros and Zaninetti, 1972, the oldest crustacean microcoprolite from the early Carboniferous of Guangxi, South China Author(s) Baba Senowbari-Daryan, Amro Gad El Rab, Katrin Heindel, Eberhard Gischler, Jörn Peckmann Abstract: Palaxius salataensis Brönnimann, Cros and Zaninetti, 1972 is described from early Carboniferous stromatolite mounds of a fore-reef slope setting from Laibin, Guangxi, South China. This is the oldest occurrence of internally structured crustacean coprolites. The geographic distribution and stratigraphic range of the ichnospecies as well as paleoecological implications

Just out @ Palaeogeography, Palaeoclimatology, Palaeoecology Residues from the Upper Permian carnivore coprolites from Vyazniki in Russia – key questions in reconstruction of feeding habits Author(s) Piotr Bajdek, Krzysztof Owocki, Andrey G. Sennikov, Valeriy K. Golubev, Grzegorz Niedźwiedzki Abstract: Residues of twenty-five coprolite fragments collected from the Upper Permian of Vyazniki (European Russia) were studied in detail. The phosphatic composition, general shape and size, and bone inclusions of these specimens indicate that medium to large-sized

Nevertheless, the latter provide significant insight into palaeoenvironmental conditions associated with the egg-laying behaviour. This study examines titanosaur-egg-bearing strata

Just out @ Journal of Vertebrate Paleontology Neither bones nor feet: track morphological variation and ‘preservation quality’ Author(s) Stephen M. Gatesy & Peter L. Falkingham Abstract: As purely sedimentary structures, fossil footprints are all about shape. Correctly interpreting the significance of their surface topography requires understanding the sources of morphological variation. Differences among specimens are most frequently attributed to either taxonomy (trackmaker) or to preservation quality. ‘Well-preserved’ tracks are judged more

Just out @ PeerJ A methodology of theropod print replication utilising the pedal reconstruction of Australovenator and a simulated paleo-sediment Author(s) Matt A. White , Alex G. Cook, Steven J. Rumbold Abstract: Distinguishing the difference between theropod and ornithopod footprints has proved a difficult task due to their similarities. Herein our aim was to produce a method where a skeleton could be more closely matched to actual fossilised footprints. The reconstructed
